Headwalls with V Notch Weir Panels

Headwalls with V Notch Weir Panels 

Did you know Althon have can manufactured precast headwalls with precast concrete V notch weirs on the spillway?! 

A V notch weir is where the physical barrier is significantly higher than the water level except for a specific V notch cut into the precast panel on the spillway of the headwall.

The V notch weir is a secondary casting and is cast to suit your specific requirements.  We are also able to cast in a galvanised mild steel or stainless steel sharp edged V notch weirs if required.  At times of normal flow all the water must pass through the V notch weir panel simplifying flow volume calculations

We can assist by providing CAD and PDF drawings of headwalls with V notch weir panels on request.

You can use our Headwall Specifier to find the headwall you require. We can then assist with pricing and design drawings detailing an appropriate V notch weir based on pipe diameter.
